GODDABD, a subject `of ,the King ofEngland, ,residing at Leicester, Leicestershire, England, ,have inventedCertain'Improvements in Eyeletingr Machines, .of which `the follow-.ingdescrip# tion, Lintonneetion .with the accompanying' drawings, is `aspeoieation, like reference characters on the `dra-Wings indicatingrlike `parts ,in the vseveral figures.

Qllhis invention `relates lto machines for insorting `fasteners vand `islherein disclosed Vas ,embodied ina inaehi-ne `adapted .to performYblind eyeleting `and invisible eyeleting as .praeticedin themanufacture of shoes. In asniuch .as .a machine of the type Vhereinillustrated -is organized to insert the eyelets downwardly from abovethe ,Work sous .to utilizethe lower tool toroleneh the barrels of theeyelets, Ait will `produce blind ,eyeleting .when ilieouter .surfaceor'upperlea-.ther is uppermost and invisible .eyeleting When the reverseside ,or lining is uppermost. IIneach oase-the eyelet will be clenchedbetween adyjaentlayers :of the work, but `when tlreiipper leather isuppermostthei'lange of .the eyelet .will lie on that side and will.therefore rbe visible ,on the. exteriorl of the.1 finished shoe, landfwhen the reve-rse sidefis uppermost the flangiefof lthe eyelet willliefen thatside and `willtherefore. be on lthe insideoffthelinishedshoe.

This patent discloses a machine equippedfor ordinary visible eyeleting, but since the mechanism and operationsfor blind` and `invisible eyeleting vdo not di`er `essentially fromthoserequired for ordinary eyleting excepting in the particulars hereinafterspecified, the accompanying drawings are restricted to a comparativelysimple disclosure which, when considered in conjunction with thecomplete organization disclosed in said patent, will be sufficient toenable one skilled in the art to practice the present invention. y iththeabove'and other objects and features in view, the invention will now.be described with reference to the accompanying drawings, and pointedoutin the claims.

'In the drawings, Fig. 1 representsanele- Vvation partly in section fofmechanism by which the article of work isv forced upon the setting toolas hereinafter described;

*Fig '2 is a plan View of mechanism utilized to givethe punch its workfeeding movement Fig. 3 isa vertical section on an enlarged scale of asetting tool for clenching invisible eyelets, showing the outer layer ofan article of work as having been forced past the clenching' shoulder ofthe setting tool, said shoulder occupying the desired position betweenadjacent layers where the clenched portion of the eyelet is intended tolie;

Fig. 4 is a plan view of the member, shown also in Fig. 3, for forcingthe outer layer of the work past` the clenching shoulder of the settingtool; Y

Fig. 5 shows the two sets as having nearly completed the clenching of aneyeletas a step subsequent to that shown b y Fig. 8;

Fig. 6 is a side elevation of a fragment of the mechanism for pressingthe layer through which the eyelet ris not to pass past the clenohingshoulder; and Y 7 is atop plan View partly in section of the structureof Fig. 6. Y

Figs. 1 and 2 of the accompanying drawings will be recognized ascorresponding in a general Away to Figs. 2l and 4 of said PatentNo.1,048,836. Thus shaft 4 carries the several cams and other actuators bywhich the work-punching andsetting tools, feeding mechanism and othermovable elements are operated. The horn 89, which is fixed, supports apunch-block 88 on which the article of work lies while being punched,and fed by punch 6 and while being eyeleted. .Punch 6 is carried uponone end of a bell crank lever 40, fulcrumed at '42 to a sleeve 43mounted upon a shaft 45 j ournaled in the machine frame and having atoggle member 44 fulcrum-ed to its other extremity. Pivoted at 46 totoggle member 44 is a co-operating toggle member 48 'fulcrumed on a pin50 provided with an adjustable eccentric bushing 52 rotatable by meansof a hand lever 54. Pivot 46 carries a roll 56 located the machine,punchk 6 will be forced down-` wardly Vinto contact,` with thepunch-block 88 to perforate the work and lateron in the vcycle Yofoperation of the machine will be withdrawn from the work. In order to-cause punchl 6 to feed the work, bell crank lever 40 is swungtransversely by mechanism which will now be briefly described. A lever(F ig. 2) fulcrumed at 61'to the machine frame carries a roll 62operating in a cam track 63 in a cam carried by shaft 4. Lever 60 isadjustably` connected as by a slide and block connection 64 to a link 65pivoted at 66 to a guide member illustrated as provided with a. pair ofguide plates 67 straddling lever 40. Thus, as lever 60 is rocked aboutits fulcrum 61, it causes the punch to move back and forth, the forwardor feeding movement of the. punch 'taking place while the punch is inengagement with the work and the rearward or idle movement of the punchtaking place after it has been withdrawn from the work, Byv adjustingthe connection between lever 60 and link 65, the extent of the feedingmovement of punch 6 may be varied. rThe foregoing mechanism is describedin detail in said Patent No. 1,048,886, to which reference may be hadfor fuller description thereof.

The clenching tool is carried by a vertically movable carrier and thepresserfoot is carried by a plunger 102 arranged to slide vertically ina fixture 104, and is normally drawn down by a tension spring 106. Alink 108 connects the upper end of the plunger with a lever 110. Thefulcrum of this lever is indicated at 112. A cam roll 114 carried by'the lever is arranged to run on a. cam 116 carriedby the shaft 4. Y

i The eyelets are inserted by a tool 51 (Fig. 5) carried by a plunger 52as in said patent,

`this tool being provided with a spindle 7 2 arranged to pick an eyeletfrom the delivery end of a raceway (not shown) by which the eyelet ispresented with its flange at the upper end of the barrel. The tool 51does not move laterally. s

The lower or setting tool remains in registration with the insertingtool and is fixed relatively to its carrier 90y but guided by thepunch-block 88. This setting tool is provided with a clenching shoulder10 formed to. pass through the lower layer or layers of the work. Apilot portion 11 pro jects upwardly from said shoulder to guide theleading end of the eyelet barrel to the clenching shoulder. The body ofthe tool, behind the shoulder 10, is preferably provided'with a seriesof fine ycircular ribs or teeth 12 having sharp edges adapted to enterthe lacing-hole in the lower layer of the work and maintain said hole inan eX- first into registration with the eyeleting tools and thenV topress thework down until the bottom layer 15 is below the clenchingshoulder 10.l 'Having thus positioned the work and the clenching tool inthe desired operative relation the clenching tool remains stationaryuntil the eyelet has been clenched, but the member 16 immediately risesfar enough to clear the pilot 11 and then swings out of registrationwith the eyeleting tools by reason of its'engagement with the roll 32.The inserting tool 51, having by this time passed its spindle throughthe eyelet in the -delivery end of the raceway (not shown) continues tomove downwardly with said eyelet which, instead of having to force onelayer of the work past the clenching shoulder as heretofore', finds thevwork and the clenching tool in the relation shown by Fig.k 3 and hasmerely to pass through the hole in the layers 13 and 14 before reachingthe clenching shoulder. The clenching operation thereupon takes placebetween the layers 14 and 15 and the inserting tool rises immediatelytoits initial position the clenching tool being timed to -descend whilethe inserting tool rises.'L The various instrumentalities are then readyto begin another cycle of operations.

The foregoing cycle of `operations and the illustrated article. of workhave been described in terms of invisible eyeleting but-it will beobvious that for purposes of blind eyeleting the work will be placed sothat the outside layer or upper leather will be at the top instead of atthe bottom and that the inside facing will then be the layer that willbe forced past the Vclenching shoulder, and the barrel of the eyeletwill then pass through the outside layer and the lining (also the eyeletstay if the upper includes one) and will be clenched between the insidefacing and the lining (for eyelet stay).
